Finished Heater Coil assy, hi temp insulation, mesh screen for Heat Gun
Finally finished restoring this heat gun! The Hi Temp Mica paper arrived last month, and today, the Stainless Steel fine mesh screen material arrived (23AWG, 0.085" square pitch) which the gun didn't have when I began rebuilding it, though my other one does. Had to cut that material into a circle, using the cutter punch from a 1" Greenlee Conduit Hole Punch as a template....just happened to be the right size to fit into the tapered flange end.
The heat gun pulls the same AC Mains Current/Wattage as my other working Raychem VC5300 (903W/7.65A @ 117VAC), it still having the original heater assembly after all these decades (bought new in 1975). It was an exercise in searching out the materials for the coil wire, how to wind the coil, find the high temp insulation material, then find the stainless steel mesh without having to buy a huge sheet of it.
